Definitions

  • the invention relates to a gate valve according to the preamble of claim 1.
  • Such gate valve with expandable plate parts as Shut-off devices are different according to the prior art Embodiments known, e.g. B. from DE-A-19 46 581.
  • the Gate valve described there has as a shut-off device for Media with a high degree of contamination and with a high proportion of dust Found in practice.
  • For pressing and releasing the Plate parts are used cylinders, in which pressure springs and hydraulic ventilation elements work in combination.
  • For use the well-known construction in slide glasses is based on the brochure No. 103 "Brillenschieber II", I / 85, the Zimmermann & Jansen GmbH, Düren.
  • the present invention is based on the object to create a gate valve of the type in question here, the regarding the arrangement for ventilating the plate parts
  • Advantages of the single-circuit system with only one Pressure medium circuit with the advantages of the described two-circuit system with two independent pressure medium circuits connects to a safe ventilation of the plate parts to ensure with minimal design effort.
  • the present invention is characterized from that each individual ventilation element two independently mutually effective pressure medium circuits are assigned, such that that if one pressure medium circuit fails, the other Pressure medium circuit is fully effective. Every ventilation element has So via a "reserve pressure medium circuit", which in the event of failure of the "normal circle” replaced this fully effective. Accordingly is the construction according to the invention a system that describes the advantages of the introduction Single-circuit system, namely the relatively small number of ventilation elements with increased opening force, and the of the described two-circuit system, namely the increased reliability, united.
  • each ventilation element with both a normal pressure medium circuit as well as a reserve pressure medium circuit connected it is in the event of failure of the normal pressure medium circuit no longer required by the Reserve pressure medium circuit inactive ventilation elements against the effect of the pressure springs assigned to them "dragged along" Need to become. This is also the reason why the edged Dual circuit system an increased number of ventilation elements with correspondingly smaller pressure springs required is.
  • the basic principle of the present invention is therefore that two independent pressure medium circuits on each ventilation element apply so that in the event of failure of one pressure medium circuit other pressure medium circuit is fully effective.
  • Fig. 1 is a hydraulic release element 10 in longitudinal section shown.
  • This ventilation element includes an in known manner on the approach, not shown, of one Plate part of the gate valve, not shown attached outer cylinder 11 with inner at the free end Ring collar 12, an approach also not shown attached to the other or opposite plate part and acting as an expanding piston inner cylinder 13 with free end outer collar 14 and one between the outer and inner cylinder in the axial direction of the same effective pressure or spreading spring in the form of a plate spring package 15.
  • the inner cylinder 13 is forming one against the Environmentally sealed annular chamber 16 between the outer and inner Cylinder and the two ring bundles 12 and 14 relative slidable to the outer cylinder 11, with introduction of pressure medium in the annular chamber 16 against the action the disc spring assembly 15 telescopically in the outer cylinder 11 in.
  • Two pressure medium lines open into the annular chamber 16 17 and 18, the pressure medium line 17 with a so-called normal pressure medium circuit and the pressure medium line 18 in connection with a so-called reserve pressure medium circuit stands.
  • the pressure medium openings 19, 20 of the two pressure medium lines 17, 18 within the annular chamber 16 are axial spaced from each other. Between the two pressure medium openings 19, 20 is an annular piston within the annular chamber 16 21 axially slidably provided.
  • One end face 22 of the Annular piston 21 is via the pressure medium line 17 and pressure medium opening 19 pressurizable, while the opposite End face 23 over the associated other pressure medium opening 20 is accessible for pressure medium. In normal operation, it is in the other pressure medium opening 20 emptying pressure medium line essentially unpressurized or by a blocking member, in particular a ball valve, from the associated Pressure fluid unit separated. That way remains in normal operation of the annular piston 21 when pressure medium is applied via the pressure medium opening 19 in its Fig. 1-3 shown normal end position with the corresponding axial intermeshing of outer and inner Cylinder.
  • the bottom of the inner cylinder 13 is with the reference number 30 marked. Both cylinders are therefore in accordance with Art a pot.
  • the illustrated embodiment includes the inner cylinder acting as a piston Bottom and outer ring collar formed in one piece, while the outer cylinder consists of two parts, namely the Bottom 29 on the one hand and the actual cylinder 11 together with the inside Ring collar 12 on the other hand.
  • the attachment of the two Cylinder 11 and 13 takes place on the approaches, not shown each with fastening screws, which are in the bottom 29 of the outer cylinder on the one hand and the bottom 30 of the inner
  • cylinders can be screwed in.
  • the screw holes are indicated in Fig. 1 with the reference numerals 31 and 32.
  • the axial distance between the two corresponds Pressure medium openings 19 and 20 in the annular chamber 16 approximately the Length of the slidably arranged within it Ring piston 21.
  • annular piston 21 is opposite the outer and sealed inner cylinder, using ring seals 33, 34. Furthermore, between the two ring bundles 12 and 14 on the one hand and the outer cylinder 11 or inner cylinder 13 on the other hand, an annular seal 35 or 36 for sealing the annular chamber 16 arranged relative to the environment.
  • the aforementioned sealants are per se known construction measures, which have no further explanation need.
  • the disc spring package, already mentioned several times 15 is formed by mutually layered disc springs.
  • the plate spring assembly is essentially centered within the inner cylinder or within the inner cylinder sleeve 13. In the transition area between the inner and the outer cylinder is centered on the plate spring assembly by one on the bottom 29 of the outer cylinder 11 arranged, namely welded on centering pin 37.
  • a screw Through a central bore 38 in the bottom 30 of the inner cylinder 13 is a screw, not shown, in the Centering bolt 37 (internal thread 39) can be screwed in.
  • This Screw is used for mounting and actuating the ventilation element in the event of total failure of the hydraulic system.
  • the inner and outer ring collar are shorter you have a slightly longer dimensioned annular chamber 16, in the annular piston 21 described can be used and described in the Way is effective.
  • the overall length of the ventilation element must not be enlarged by the measures mentioned will. Accordingly, the dual-circuit ventilation elements described are suitable also for retrofitting conventional gate valves, especially slide glasses.
  • FIG. 6 shows an alternative embodiment of a two-circuit ventilation element 10 shown in a schematic longitudinal section. This differs from the one described above Venting element primarily in that it does not have an annular piston. Instead, the normal circuit pressure medium line opens on the star side 17, reserve circuit pressure medium line 18 and one third line 42 into the annular space 16, the pressure medium openings marked with the reference numbers 19, 20 and 46 are.
  • the two pressure medium lines 17 and 18 each have a spring-loaded check valve 40 or 41, the one pressure medium flow only into the annular space 16 allowed, the pressure medium flow through the pressure medium lines 17 and 18 associated, namely between the check valves 40, 41 and a tank 47 arranged pressure medium pumps 48 and 49 is effected.
  • FIG. 7 corresponds in principle to that according to Fig. 6. However, it differs from this in that they have no third fluid line 42 and no check valves 40, 41 in the "normal circuit” - and “Reserve circuit” pressure medium lines 17 and 18. Instead, there are 2/2-way valves in the lines 17 and 18 44 and 45 arranged, each in the open position can flow through in two directions. With that, the two are Lines 17 and 18 each for both the pressure medium supply in the annular space 16 as well as for the pressure medium removal the annular space 16 suitable, independently of each other as "Normal circuit” line or "reserve circuit” line.
  • pumps 48 and 49 must of course each be designed so that they can flow through pressure medium in the inactive position are. Accordingly, if necessary, under the action of the spring 15 pressure medium from the annular space 16th through the open valve 44 or alternatively through the open Valve 46 and the respectively assigned pump 48 or 49 are pressed through into the tank 47.
